The flag of Portugal is divided into two main parts: a green field on the left (hoist side) and a red field on the right (fly side). At the center of the flag is the Portuguese coat of arms, which is positioned where the two colors meet. The coat of arms includes a shield with seven castles and five shields, symbolizing significant historical events and victories. The flag's design is rich in symbolism, representing the country's history and heritage. The green symbolizes hope, while the red represents the blood of the nation. The overall design is a proud representation of Portugal's identity and history.
